Member: 517318 Status: Offline Thanks Meter: 88 | Hello I didn't do the job. I know that if I downgrade the version the phone dies. I didn't explain it correctly, I should have asked: Is there a possibility to unlock the bootloader? I have no experience with this model, it is not common in my country. I can't find a way to unlock the bootloader |
